摘要：

In this work, the hollow zinc oxide (ZnO) spheres were synthesized by template free solvochemical method and applied as electrode materials for fabricating the electrical chemical sensor. The use of ethylene glycol (EG) and ethanol solvent were important to achieve the hollow ZnO structures. The crystalline and structural analysis evidenced that the synthesized materials were well-crystalline with typical wurtzite ZnO crystal. The electrochemical properties of the fabricated electrical chemical sensor were tested by current-voltage characterization. A sensitivity of similar to 361.2 mu AmM(-l )cm(-2), detection limit of similar to 20.8 nM and correlation coefficient (R) of similar to 0.97752 were achieved by the fabricated electrical sensor based on hollow ZnO spheres as working electrode for the detection of hydrazine chemical.
